Detailed Description

In order to make the present invention better understood by those skilled in the art, the technical solutions of the present invention are further described below with reference to the accompanying drawings and examples.

As shown in fig. 1-2, the utility model discloses a sheet metal component pressure riveting frock, including nut fixed column 1 and last compact heap 2, 1 one end of nut fixed column has reference column 101, the 1 other end of nut fixed column is equipped with mounting hole 102, 2 upper portions of last compact heap are equipped with step hole 201 and via hole 202, the lower part is equipped with recess 203 and lower step hole 204, install excel power in the lower step hole 204 and glue post 205, excel power glues post 205 and is equipped with through-hole 206, go up step hole 201 and install screw 207, screw 207 passes via hole 202 and through-hole 206, screw 207's lower extreme threaded connection has clamp plate 3, clamp plate 3 and recess 203 slide to match, clamp plate 3 is equipped with boss 301, boss 301 and through-hole 206 phase-match, and with screw 207 threaded connection.

In this embodiment, when a sheet metal part press riveting tool is used, the nut fixing post 1 is first installed on the machine table through the positioning post 101, the press riveting nut 5 is installed in the installation hole 102, the screw 207 is then installed in the upper step hole 201 through the through hole 202, while the cap screws 207 are inserted through the through holes 206 of the cap screws 205 to mount the cap screws 205 in the lower step holes 204, then the pressing plate 3 is connected with the screw 207, finally the sheet metal part 4 passes through the pressure riveting nut 5, under the action of the pressure from top to bottom, the high-strength rubber column 205 is shortened, the pressing plate 3 slowly slides into the bottom of the groove 203 of the upper pressing block 2, the arc 402 of the sheet metal part 4 gradually enters the groove 203 of the upper pressing block 2, the pressure rivet nut 5 gradually compresses under the condition that the sheet metal part 4 retreats to the bottom, meanwhile, the side wall of the groove 203 blocks the edge 401 and the arc 402 of the sheet metal part 4, so that the sheet metal part is not deformed and bent; after the pressure is released, the high-strength rubber column 205 rebounds to push out the pressing plate 3, so that the sheet metal part 4 is pushed out, and the production of products is realized.

The depth of the upper stepped hole 201 is preferably 3mm higher than the height of the head of the screw 207, and such design ensures that the screw 207 cannot push out of the upper stepped hole 201 to affect operation when riveting, and actually, other protective measures can be considered according to specific conditions.

Preferably, the edges of the groove 203 are rounded 208, such a design facilitates the sheet metal part to slide into the groove 203, and in fact, other structures facilitating sliding can be considered according to specific situations.

Preferably, lower step hole 204 and the rubber column 205 clearance fit installation of excelling in, such design, the rubber column 205 of excelling in when guaranteeing to press to rivet has the space of inflation when compressing, in fact, also can consider other spaces of stepping down according to particular case.

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention.
